In the accompanyiing -.drawings which illustrate two forms of floorconstructionmade in accordance with my invention, Figure 1 is a verticalcross section through a. ortion of a railway car to which my device 1sapplied; Figure 2 is a detail view of the cli Figure-3 is a sectionalview similar to igure 1 but showmga modlfication; and

'At'somedistance from the edge of the flange 6 the floor' board'has formedtherein a bolt hole 8 terminating at its upper end in an enlargement 9.Extending up wardly through the bolt hole 8 is a bolt 10 having a squareor other non-circular portion 11 adjacent to its head 12. This squareportion-ll is adapted to be drawn u into'the a correspo ding'ly shapedopening 13 in the clip 14.

The clip 23, as shown in Figure-4,. is substantiallytriangular in shape and-is provided with a "downwardly bentedge 24 forengaging withthe under face of the flange 6. A nut 25 enga threaded endof the bolt and at 26 to form a nut lock.

It will be evident that'in both the con- -structio'ns set forth the boltis held from rotation in the floor board and the clip from rotating onthe bolt and that consequently the cli will be held in-proper relationtothe sil without anymeans 'on the clip for engaging either jwlth' theedge of the sill or with the floor board. toprevent-rotation.
